Car won't hold idle ?!?!
 

hey guys

got my car finally started today, after switching from aem ems back to stock ecu and maf setup. runs good but when i come to a stop i put the car into neutral and come to a stop sign or light and the car will just drop rpm's and **** off. we tried raising the idle which helped wen just turning on car and sitting. IDK if it has something to do with the moving idle of car or what not.

i am running a greddy type rs which recircs back into the intake. no lines are pinched or anything.

let me know what you guys think

thanks.

do you have cams?

ya i have 272's the thing is i switched from aem ems to a stock ecu and maf setup and it already has a tune from another car but it's setup with same things as mine. and i know every car is not the same, but im just surprised it won't stay idled. goign wot the car see's 11.4=11.5 a/f and only 2 counts of knock which is not bad, but wont stay idle lol.

thats your problem then... if the tune isnt car specific, try refining some of the tables and see if that fixes it... what is your idle rpm set to?
